A blue zone is a region in the world where people are claimed to have exceptionally long lives beyond the age of 80 due to a lifestyle combining physical activity, low stress, rich social interactions, a local whole-foods diet, and low disease incidence. Examples of blue zones include Okinawa Prefecture , Japan; Nuoro Province , Sardinia, Italy; the Nicoya Peninsula , Costa Rica; and Icaria , Greece. The name "blue zones" derived simply during the original survey by scientists, who "used a blue pen on a map to mark the villages with long-lived population."
55-414: The concept of blue zones with longevity has been challenged by the absence of scientific evidence, and by the substantial decline of life expectancy during the 21st century in one of the first proposed blue zones, Okinawa. A 1999 study of elderly people living on Sardinia found a prevalence of 13 centenarians per 100,000 population, indicating unusual longevity. A 2004 followup report showed that longevity
110-519: A congratulatory letter to Reverend Thomas Lord of Horncastle , Lincolnshire, in a newspaper clipping, declaring, "I am commanded by the King to congratulate you on the attainment of your hundredth year, after a most useful life". The practice was formalised from 1917, under the reign of King George V , who also sent congratulations then sent by a telegram on the attainment of a diamond wedding anniversary (or jubilee) marking 60 years of marriage. During

In Greece, wishing someone Happy Birthday ends with the expression να τα εκατοστήσεις ( na ta ekatostisis ), which can be loosely translated as "may you make it one hundred birthdays". In Sri Lanka, it is a custom to bless as "you may live 220 instead of 120". In many countries, people receive a gift or congratulations from federal/state institutions on their 100th birthday. As of 2019, there were an estimated 72,000 centenarians living in

In Ireland, centenarians can receive a €2,540 "Centenarians' Bounty" and a letter from the president of Ireland , even if they are resident abroad . Irish people celebrating their 101st birthday may also receive a special silver minted coin with a quote by a famous Irish writer or poet. Centenarians born in Italy receive a letter of congratulations from

A preliminary study carried out in Poland showed that, in comparison with young healthy female adults, centenarians living in Upper Silesia had significantly higher red blood cell glutathione reductase and catalase activities, although serum levels of vitamin E were not significantly higher. Researchers in Denmark have also found that centenarians exhibit a high activity of glutathione reductase in red blood cells. In this study,

The ceremony is co-sponsored by the Harvard Computer Society, the Harvard–Radcliffe Science Fiction Association and the Harvard–Radcliffe Society of Physics Students. Throwing paper planes onto the stage is a long-standing tradition. For many years Professor Roy J. Glauber swept the stage clean of the airplanes as the official "Keeper of
495-459: A rigorous scientific method. Centenarian A centenarian is a person who has reached the age of 100 years. Because life expectancies worldwide are below 100, the term is invariably associated with longevity . The United Nations estimated that there were 316,600 living centenarians worldwide in 2012, and 573,000 in 2020, almost quadruple the 2000 estimate of 151,000. As world population and life expectancy continue to increase,

Other ancient accounts of Democritus agree that the philosopher lived at least 90 years. The case of Democritus differs from those of, for example, Epimenides of Crete (7th and 6th centuries BC), who
605-587: A special occasion." Each few years the card was updated with a current updated picture of the Queen to ensure people did not receive the same card more than once. The Queen further sent her congratulations on one's 105th birthday and every year thereafter as well as on special wedding anniversaries. While the number of centenarians per capita was much lower in ancient times than today, the data suggest that they were not unheard of. Estimates of life expectancy in antiquity are far lower than modern values mostly due to

There are 75 people in recorded history who have indisputably reached 115. Only three of the people who have reached 115 are men. Tomiko Itooka , Inah Canabarro Lucas , Ethel Caterham and Okagi Hayashi are the only verified people currently alive who have reached

770-428: Is said by Bernold of Constance to have lived past 100 years ( iam maior centenario ). Research in Italy suggests that healthy centenarians have high levels of both vitamin A and vitamin E and that this seems to be important in causing their extreme longevity. Other research contradicts this, however, and has found that this theory does not apply to centenarians from Sardinia , for whom other factors probably play
825-526: Is said to have lived an implausible 154, 157, or 290 years, depending on the source. Other ancient Greek philosophers thought to have lived beyond the age of 90 include Xenophanes of Colophon ( c. 570/565 – c. 475/470BC ), Pyrrho of Ellis ( c. 360 – c. 270 BC ), and Eratosthenes of Cirene ( c. 285 – c. 190 BC ). Also, the Greek rhetorician Isocrates of Athens (436-338 BC) lived 97/98 years and

In Taiwan, people aged 100 or above receive a golden pendant necklace on Chong Yang Festival each year from the president and Ministry of Health and Welfare . German centenarians receive
1265-624: The Ig Nobel Awards are veiled criticism of trivial research, history shows that trivial research sometimes leads to important breakthroughs. For instance, in 2006, a study showing that one of the malaria mosquitoes ( Anopheles gambiae ) is attracted equally to the smell of Limburger cheese and the smell of human feet earned the Ig Nobel Prize in the area of biology. As a direct result of these findings, traps baited with this cheese have been placed in strategic locations to combat
1320-517: The Nobel Prize categories of physics, chemistry, physiology/medicine, literature, economics, and peace, but also other categories such as public health, engineering, biology, and interdisciplinary research. The Ig Nobel Prizes recognize genuine achievements, with the exception of three prizes awarded in the first year to fictitious scientists Josiah S. Carberry , Paul DeFanti, and Thomas Kyle . The awards are sometimes criticism via satire, as in

However, the U.S. Census Bureau claimed in 1999 that as many as a third of people stating their age as over 100 might be exaggerating. In the United States, centenarians may request a letter of congratulation from the president of the United States to mark their longevity. Jimmy Carter became the first former president to reach
1430-540: The United States. The UN estimated in 2012, as a result of these adjustments, that there were only 316,600 centenarians worldwide. The following table gives estimated centenarian populations by country, including both the latest and the earliest known estimates, where available. A study which received a 2024 Ig Nobel Prize found these numbers are inflated by welfare and pension fraud and poor record-keeping, neither of which are uniform across jurisdictions. A supercentenarian , sometimes hyphenated as super-centenarian,

Hosius of Córdoba , the man who convinced Constantine the Great to call the First Council of Nicaea , reportedly lived to age 102. A rare record of an ordinary person who lived to be a centenarian is the tombstone of Roman British legionary veteran Julius Valens, inscribed "VIXIT ANNIS C". In the medieval period, Albert Azzo II, Margrave of Milan (d. 1097)
1925-491: The far greater incidence of deaths in infancy or childhood. Those who lived past early childhood had a reasonable chance of living to a relatively old age. The assumption of what constitutes "old age", or being "elderly", at least, seems to have remained unchanged since antiquity, the line being generally drawn at either sixty or sixty-five years; Psalm 90 :10 in the Hebrew Bible appears to give seventy to eighty years as
1980-593: The gene FOXO3 A is known to have a positive effect on the life expectancy of humans, and is found much more often in people living to 100 and beyond – moreover, this appears to be true worldwide. Men and women who are 100 or older tend to have extroverted personalities, according to Thomas T. Perls, the director of the New England Centenarian Study at Boston University. Centenarians will often have many friends, strong ties to relatives and high self-esteem. In addition, some research suggests that

For instance, Cicero's wife Terentia was reported by Pliny the Elder to have lived from 98 BC to 6 AD, 103 years. Regnal dates of Bronze Age monarchs are notoriously unreliable; the sixth dynasty Egyptian ruler Pepi II is sometimes listed as having lived c. 2278 – c. 2184 BC , as he
2200-789: The marketing company, Blue Zones LLC, adding Loma Linda , California, to the list of blue zones. Buettner described the Seventh-Day Adventist community there as having unusual longevity due putatively to a healthy lifestyle and plant-based diet . In 2020, the Blue Zones company was acquired by the Seventh-Day Adventist health care system, Adventist Health . Recent years have seen the blue zone concept featured in initiatives in industries such as insurance, technology and tourism. The concept of blue zone communities having exceptional longevity has been challenged by

The tradition of royal congratulations continued in 1908, when the secretary for King Edward VII sent
2475-572: The offspring of centenarians are more likely to age in better cardiovascular health than their peers. Lymphoblastoid cell lines established from blood samples of centenarians have significantly higher activity of the DNA repair protein PARP ( Poly ADP ribose polymerase ) than cell lines from younger (20 to 70 years old) individuals. The lymphocytic cells of centenarians have characteristics typical of cells from young people, both in their capability of priming
2530-428: The original study of centenarians living in 14 mountain villages of Sardinia (the first proposed blue zone), the research team developed an Extreme Longevity Index (ELI) representing the ratio between the number of eventual centenarians born between 1880 and 1900, and the total number of births recorded during the same time interval for the region. The ELI was defined as the number of centenarians per 10,000 newborns, and

2805-630: The typical Japanese diet, which is particularly low in refined simple carbohydrates, and to hygienic practices. The number of centenarians in relation to the total population was, in September 2010, 114% higher in Shimane Prefecture than the national average. This ratio was also 92% higher in Okinawa Prefecture . In Okinawa, studies have shown five factors that have contributed to the large number of centenarians in that region: Although these factors vary from those mentioned in

#17327659864092860-565: Was concentrated in the Nuoro province of Sardinia, specifically in its mountain regions where locally-born men lived longer than those in the rest of Sardinia, although reasons for the longevity were unknown. Beginning in 2005 in collaboration with author Dan Buettner , the list of blue zone regions was extended from Sardinia to include Okinawa, Nicoya in Costa Rica, and Icaria in Greece. In
2915-734: Was one per 3,522 people in 2008. In Japan, the number of centenarians is highly skewed towards females. Japan in fiscal year 2016 had 57,525 female centenarians, while there were 8,167 males, a ratio of 7:1. The increase of centenarians was even more skewed at 11.6:1. The total number of centenarians in the world is uncertain. The Population Division of the United Nations estimated that there were 23,000 in 1950, 110,000 in 1990, 150,000 in 1995, 209,000 in 2000, 324,000 in 2005, 455,000 in 2009, and 935,000 in 2024. These older estimates, however, did not take into account downward adjustments of national estimates made by several countries such as

Costa Rica’s “Blue Zone” is now being re-examined and shown to be a result of cohort effects. Harriet Hall , writing for Science-Based Medicine , stated that there are no controlled studies of elderly people in the blue zones, and that blue zone diets are based on speculation, not evidence through
3025-873: Was used to determine the probability that any person born in that municipality would reach 100 years old while remaining mentally and physically functional. Another longevity index applied was the Centenarian rate (CR) for the 1900 birth group (number of persons surviving to 100 years old per 10,000 people alive at age 60) in December 2000. The Sardinia and Okinawa blue zones had CR values for men substantially higher compared to several other countries, whereas values for women were mostly above those in other countries, while comparable to others. Several possible errors or limitations exist for these estimates, such as failure to validate accuracy of ages, unreliable interviews or missing birth records. In 2008, Dan Buettner established
